Title: Method for adjusting a position of a solid-state image detector in a given image-forming optical system
Inventor: OHURA KOUJI
IPC: H04N17/00
Filed: 1996-03-18
Granted: 1999-05-25
Abstract: A three-dimensional resolution chart is used to adjust the position of a solid-state image detector 4 in a given image-forming optical system.  A plurality of blocks 10a are provided on an upper surface of a resolution chart 10. Each block 10a has an adjusting pattern A-D depicted on a slant surface thereof.  An image of each adjusting pattern A-D is formed on the solid-state image detector 4 through a master lens 2. The contrast integration value F is calculated based on the image of the adjusting pattern at each of a plurality of designated areas hj (j=1---n) on the slant surface of each block 10a provided on the resolution chart 10, to find out a specific position on each block where the contrast integration value F becomes maximum, thereby identifying the specific position as focus point of the master lens 2.  The back focus of the solid-state image detector 4 is calculated based on thus obtained focus point.   An optimum gradient  (.alpha., .beta.)  of  the  solid-state  image detector 4 is calculated based on three-dimensional relationship between plural focus points of the master lens 2 detected on the plural blocks 10a. Finally, each positioning mechanism 11 adjusts each  solid-state  image  detector  4  to  the  calculated  optimum position or at the optimum gradient.

Title: Semi-batch emulsion process for making diene rubber latex, rubber latex made thereby, and graft copolymer made therefrom
Inventor: LOWRY VERN
IPC: C08F2/24
Filed: 1996-08-15
Granted: 2008-03-18
Abstract: A semi-batch process is provided for making a diene rubber latex. The process involves (a) providing an amount of an initial liquid batch composition (containing water, emulsifier and diene monomer), sufficient to occupy from 50 to 80 volume percent of a pressure reaction vessel based on the total volume of the vessel, (b) feeding to the vessel a liquid feed composition containing diene monomer and initiator, (c) providing cooling to the vessel to cool the liquid and vapor therein, and (d) reacting the diene monomer to a final diene monomer conversion level of at least 80 mol percent based on the total moles of diene monomer used in the reaction, and the final liquid volume level in the vessel being at least 80 volume percent based on the total volume of the vessel. The process allows for a high initial reaction rate which peaks early in the process when efficient vapor phase cooling is maximized, and maintains a low latex viscosity throughout the process thereby providing efficient liquid phase cooling during latex in the process. The present process allows for higher levels of production over batch utilizing the same vessel volume. A rubber latex is also provided having a narrow particle size distribution, and a vinyl aromatic-diene rubber graft copolymer is provided exhibiting certain advantageous properties.
